Bright eye makeup reigned supreme at shows like Derek Lam and Peter Som. This season, give boring brown and black eyeliner some time off, and amp up your lash lines with a swipe of sunny yellow or electric orange. To make it budge-proof, steal this trick we picked up backstage at Som's show from makeup guru Tom Pecheux: Coat lids with a thin layer of concealer and powder before applying Technicolor liner, and save greasy eye creams for bedtime. To get Crayola-inspired eyes, try MAC Chromaline in Primary Yellow.
